WATER-HEATER.

SPECIFICATION forming part of Letters Iatent No. 446,301, dated February10, 1 891.

Application filed June 27, 1890.

To all whom it may concern:

Be it known that I, THOMAS EDWARD SPEN- CER, manufacturer, a subject ofthe Queen of Great Britain, residing at the city of Toronto, in thecounty of York, in the Province of Ontario, Canada, have inventedcertain new and useful Improvements in lVater-Heaters; and I herebydeclare the following to be a full, clear, and exact description of thesaine.

The object of my .invention is the provision ot` a simple and effectivedevice of this character whereby all the heat generated is consumed andutilized.

\Vith this object in view the invention consists in the improvedconstruction and combination ot' parts, as hereinafter more fullydescribed.

In the accompanyil'lg drawings,Figure l is a sectional view of myimproved heater. Fig. 2 is a horizontal section on the line .9c 0c, Fig.l; and Fig; 3 is a horizontal section on the line y y, saine figure.

Like letters of reference refer to like parts throughout the severalviews.

Referring' to the drawings, the letter A indicates the outer casing, andB an inner defiecting-casing having an open top and bottom, connected atits upper end to the outer easing by means of an annular-concave flangeo and at its lower end by an annular convex fiange b.

The letter C indicates an upper waterchamber, the top of which isdome-shaped and has a depending annular ange c, which terminatessufficiently high above the upper flange l) of the defiectingcasing asto form a passage for the flame, gas, and heated air.

The letterD indicates a lower water-chainber, having its bottomdome-shaped and extending upwardly to form an annular flange d, whichterminates at a point sufficiently below the lower flange b ot' thededecting-casing as to leave a passage therebetween for the heated air.

The upper and lower water-chambers are connected by means of tubularpipes E, said chambers also provided, respectively, with a flow-pipe Fand a supply-pipe Gr.

Tithin the outer casing, and beneath the lower water-chamber, is aburner H. The flame, gas, and heated air generated by this burner belowthe base-chamber pass across Serial No. 356,981. (No model.)

the dome-shaped bottom, and, coming in contact with the base-fiange b ofthe deflectingcasing, are directed inward an d upward about the pipes E,where they are permitted to ascend to and across the under side of theupper water-chamber C and through the passage t'orined between theoverhanging flange c and the flange b of the defiecting-casing, andfinally into the smoke-chamber I, whence they are carried off in theusual way. By this arrangement of parts I am enabled to consume all theheat generated by the burner, as the heated gas and air, in coursingbetween the pipes E and water-chamber, are entirely absorbed by the ironchambers filled with water.

Having thus described my invention, what I claim, and desire to secureby Letters Patf ent of the United States, is-

1. In a heater for gas-stoves, 'the combination of an outer casing,upper and lower water-chambers, pipes for connecting the same, and acylindrical deflector surrounding the connecting-pipes, said deflectorconnected at its top and bottom within the outer casing, forming aclosed annular chamber, substantially as set forth.

2L In a heater for gas-stoves, the combination of an outer casing, upperand lower water-chambers, pipes for connecting the saine,

and a cylindrical deflector surrounding the connecting-pipes, saiddeflector provided at its upper and lower ends, respectively, withconcave and convex fianges connecting the same with the outer casing,substantially as set forth.

3 In awater-heater forgas-stoves,the combination of an outer casing, aninner deecting-casing provided at its upper and lower ends with concaveand convex flanges respectively connecting the same with the outercasing, upper and lower water-chambers pro; vided with projectingvertical Hanges, tubular pipes connecting the same, a flow-pipe tted tothe upper chamber,a supply-pipe entering the lower water-chamber, and aburner, substantially as set forth.
